"The steamroller is still many inches away. I'll make a plan once it actually starts crushing my toes."
You are in danger. Unless you estimate the odds of a breakthrough at <5%, or you already have enough money to retire, or you expect that AI will usher in enough prosperity that your job will be irrelevant, it is straight-up irresponsible to forgo making a contingency plan.
My contingency plan is that if AI leaves me unable to get a job, we are all fucked and society as a whole will have to fix the situation and if it doesn’t, there is nothing I could have done about it anyway.
